Patent number: 10991666Abstract: A location displacement of an electrode of a device relative to an electrode pad of a semiconductor element is detected based on a conduction state between the electrode pad of the semiconductor element and the electrode of the device. The electrode pad of the semiconductor element is segmented into multiple portions and a first pad through a fourth pad uniformly arranged. A location displacement detector determines that no location displacement has occurred when the electrode pad of the semiconductor element is conductive to the electrode of the device, and determines that a location displacement has occurred when the electrode pad of the semiconductor element is non-conductive to the electrode of the device.Type: GrantFiled: December 11, 2018Date of Patent: April 27, 2021Assignee: SHARP KABUSHIKI KAISHAInventors: Yuta Ikawa, Kenichi Murakoshi, Hiroyoshi Higashisaka, Shigeyuki Akase

Patent number: 8297826Abstract: Provided is a backlight unit capable of reducing luminance unevenness. The backlight unit includes a plurality of dot light sources and a light guide plate in which a predetermined side surface serves as a light incident surface for introducing light from the plurality of dot light sources. The plurality of dot light sources are classified into a first light source group and a second light source group. A mount point of the first light source group and a mount point of the second light source group are displaced from each other in a thickness direction of the light guide plate. A total luminance of the first light source group is higher than a total luminance of the second light source group.Type: GrantFiled: December 2, 2010Date of Patent: October 30, 2012Assignee: Sharp Kabushiki KaishaInventors: Kenichi Murakoshi, Tsuyoshi Ono, Hidekazu Fujii, Yasuaki Hirano, Makoto Hirota

Patent number: 8162508Abstract: An LED substrate comprises holes having an elliptical shape through which fixing screws are inserted. The fixing screw has a head portion, an unthreaded neck portion whose diameter smaller than that of the head portion, and a threaded shaft portion whose diameter smaller than that of the neck portion. A major axis of the hole is larger than the diameter of the head portion, and a minor axis thereof is smaller than the diameter of the head portion and larger than the diameter of the neck portion. The LED substrate further comprises counterbored recesses to which anchoring claws provided in a cabinet are fitted. A width of the counterbored recess in a direction of the major axis of the hole is larger than that of the anchoring claw. The counterbored recesses are formed on both of two sides of the LED substrate facing each other in a first direction.Type: GrantFiled: March 2, 2010Date of Patent: April 24, 2012Assignee: Sharp Kabushiki KaishaInventors: Kenichi Murakoshi, Hiroyuki Nabesawa, Atsushi Yamashita
